I replaced my right front hub, U- Joints on both sides and my steering dampener on my 98 JGC w/ 4.0L 6cyl last weekend. Now when I go in reverse the first turn I make makes a clunk sound… it only happens once. Then it when I put it in drive and move forward, the first turn I make makes the same sound and I stress it only happens on the first turn in either direction. After the initial clunks the jeep runs very smooth. To get my steering dampener out I had to pound on it w/ a hammer where it connects to the drang link, could I have bent something or could this be a tie rod problem (I plan on replacing them soon anyway).
Any/All help is appreciated.

kinda sounds like you got something binding....going from reverse to forward & when turning??? seems like binding to me....maybe the front driveshaft is worn? you could take it out & try driving without it & see if it still does it.

i seem to have the similar problem except mine is more than one clunk....i replaced the hub assembly noise goes away, few weeks later the noise returns, replace the hub assembly noise goes away, comes back again...i have yet to figure it out_________________96 Cherokee 7.5 inch TnT long arm Locked F/R, D44 rear, 4.56s, 35x12.50 Muds/36x12.50 TSLs

My 94 Grand cherokee just started doing that since the last time i went out 4x4ing. I've tore the front end apart and yet to have located the source. Mine is more located to the passenger front. Only clunks once when changeing direction..

I don't have the all time 4wd. but a mechanic friend of mine said to check the drive shaft U-Joints so I'll post back when I get to that. In the next day or so_________________Clean your engine. It will thank you.
